Abstract:
In light of substantial new discoveries of hot subdwarfs by ongoing
spectroscopic surveys and the availability of the Gaia mission Early
Data Release 3 (EDR3), we compiled new releases of two catalogues of
hot subluminous stars: The data release 3 (DR3) catalogue of the known
hot subdwarf stars contains 6616 unique sources and provides
multi-band photometry, and astrometry from Gaia EDR3 as well as
classifications based on spectroscopy and colours. This is an increase
of 742 objects over the DR2 catalogue. This new catalogue provides
atmospheric parameters of 3087 stars and radial velocities of 2791
stars from the literature. In addition, we have updated the Gaia Data
Release 2 (DR2) catalogue of hot subluminous stars using the improved
accuracy of the Gaia EDR3 data set together with updated quality and
selection criteria to produce the Gaia EDR3 catalogue of 61,585 hot
subluminous stars, representing an increase of 21785 objects. The
improvements, compared to Gaia DR2, in Gaia EDR3's astrometry and
photometry have enabled us to define more sophisticated selection
functions. In particular, we improved hot subluminous star detection
in the crowded regions of the Galactic Plane as well as in the
direction of the Magellanic Clouds by including sources with close
apparent neighbours but with flux levels that dominate the
neighbourhood.
Description:
Here we present new releases of the catalogue of known hot subdwarfs
(DR3) and the catalogue of hot subluminous star candidates (DR2) based
on improved data from Gaia EDR3 (Gaia Collaboration,
2021A&A...649A...1G 2021A&A...649A...1G, Cat. I.350), new results from spectroscopic
surveys, and an extensive literature search.
